WindowsAPICodePack to display file preview from EPDM Vault

I have an external vb.net app that previews Windows files in the same way Windows Explorer sees them.  See code below:

References:

     Microsoft.WindowsAPICodePack.dll

     Microsoft.WindowsAPICodePack.Shell.dll

Private Function GetWindowsPreviewBitMap(strFullFilePath As String) As System.Drawing.Bitmap

     Dim BitMapResult As System.Drawing.Bitmap = Nothing

     Dim ShellItem As ShellObject = Nothing

          If System.IO.File.Exists(strFullFilePath) Then

               ShellItem = ShellFile.FromFilePath(strFullFilePath)           

               BitMapResult = ShellItem.Thumbnail.ExtraLargeBitmap

          End If

     Return BitMapResult

End Function

This function works great....Except in the Vault where EPDM appears to have a grip on the shell.

I end up with icon displays in my app when I point to a file in the Vault.  I don't want to write a separate previewer for AutoCAD,SolidWorks,PDF,Visio,Word,Excel,Powerpoint,Publisher,etc etc.

Any ideas out there?
